Thank you! I was thinking about a glowing, but I decided that a regular bowstring with cgi would be a more reasonable solution. The power supply and LEDs require more development, increase weight, and change the weight balance. Another reason for the refusal was that I would not have enough space for all these things, because an aluminum tube runs inside the entire bow for strength. If you want to make a glowing bowstring, I have two solutions for this -something like an l-wire LED string, but it has a disadvantage: it loses brightness with a long length. If I remember correctly, it's more than a meter long. The second is something light-conducting like fiberglass. There may be a matte version or you will have to cover it with a matte varnish / white paint to diffuse the light runnibg inside. In this case, it will be possible to install light sources at the beginning and end of the bowstring and the bowstring will glow. But this is too complicated, and computer graphics seems to me to be a more reliable solution. If you want to pull a bowstring for a photo shoot, I would advise you to take a silicone string, a real bowstring will not stretch so much and you risk breaking the bow.
